Terminal Blocks - Barrier Blocks

Barrier blocks are a class of terminal blocks in the family of connectors. They are designed to provide high electrical, mechanical and vibration performance under strenuous temperatures and environmental conditions.Barrier blocks use a system that includes interlocking female and male barriers. The barrier blocks are made of either molded or machined plastic to provide reliable electrical connection between two wires or components. The interlocking female and male barriers create a tight electrical connection, which prevents stray electrons or misplaced wires from causing any electric circuit.Barrier blocks come in different sizes, ranging from small to very large, with single or multiple row configurations. The maximum current rating per row or through-hole can range from 8 A to 30 A. The most common type of barrier block is DIN-46277-1, which has common hole sizes of 2.54 mm, 4.8 mm, or 9.56 mm. This type of barrier block is available in different versions, providing electrical isolation, mounting base, earth groundscrews, mounting tags, lugs, push-in terminals, and more.Barrier blocks come with different features, such as copper field, gold plated fields, insulation coating, etc. Some barrier blocks are also available with latching modules for easier installation and secure termination.The working principle of barrier blocks is based on controlling the electrical connection between wires. The female and male connectors of the barrier blocks are created to offer secure electrical connection by preventing electrical leakage. The electrical signals flow through the connector and are connected to the other terminals, where the electric current flows and activates the circuit.Barrier blocks are mainly used in the automation, electrical and automotive industries, among other application fields. In the automation industry, they are mainly used to provide secure electrical connections, so that the automation systems function properly. In the electrical industry, they are used to maintain and control, the electrical connectivity between the terminals in circuitbreak panels.In automotive industry, barrier blocks are widely used in making electric wiring harnesses, connecting electrical components, and providing secure electric connections between the car and the rest of the electrical system.Barrier blocks are used in many other application fields. They are used for communication and data transmission, industrial machines, plant products, vacuum systems, pharmaceutical devices, power supplies, testing instruments, and for electrical connections in general.Barrier blocks are very important components for any application that needs a secure electrical connection between two parts. They provide durability and reliable performance and they can be found in a wide range of applications and industries.
